HENRY J'. LIST, OF SAN FRANCISCO, CALIFORNIA.

AERDPLANE.

To all whom 'it may concern:

Be it known that I, HENRY J. Lisi', a subject of the Emperor of Austria-Hungary, residing in the city and county of San Francisco and State of California, have invented a new and useful Aeroplane, of which the` following is a specification.

My invention relates to aeroplane construction and its object is to provide greater etliciency, durability and vsimplicity of manipulation.

The suspension of the aero-plane is dependent, while in flight, upon the horizontal plane as heretofore used by air crafts but I employ a novel construction of circular bands or hoops 'so arranged and connected as tio provide resiliency and also durability in case the frame of said craft should accidentally or otherwise come into violent contact with the earth or any other object.

For a full comprehension of my construction, reference should be had to the accompanying drawings, in which- F lgure 1 1s a side elevation of my aeroplane. Fig. 2 1s a plan View thereof. Fig.

. 3 is a rear end elevation. Fig. 4 is a plan View of my double, quintuple, spherical construction, the propellers being ehminated.

f Fig. 5 is a side elevation of Fig. 4. Fig. G

` forward movement.

'vided at the lower portion of the frame 10 is a rear elevation of Fig. 4. Fig. 7 is a detailed View of the central, vertical ring of the quintuplc construction, showing the drivingshaft andV its connections with the propeller shafts, the' driving engine, fuel tanks and plane manipulating mechanisms.

A rigid horizontal plane 11 is secured to the frame'lO of the machine. Fivotcd vertical planes 2 and 2i are ,secured to the frame 10 in a plane at right angles to the horizontal planes A11. A second horizontal plane l is pivoted at its center to the framework 10 of the machine. Within the center of the rigid plane 11 are rigidly secured ve circular hoops 3. In the center of the hoops 8 are five smaller hoops 4. Within the space formed by the circular hoops 4 and the circular hoops 3, are propellers 5 rotated by the drive shafts 5 (Fig. 7). Fore and aft propellers 6 are further provided to give the ship a forward movement. Two smaller rear propellers 8, driven by shafts 7 are provided to give the ship van upward and Runners 9 are pro in order to maintain the craft in an upright position when on the ground.

Specification of Letters Patent.

Application filed March 2, 1912.

Patented Aug. 6, 1212.. serial No. 681,265.

An engine 12 of any suitable type is pro- .vided to drive the drive shaft 5 which through the medium of the beveled gears 14 and 15, drives the propellers 5. Hand wheels 16 (Fig. 7) are provided for the manipulation of the horizontal. pivoted plane 1. Fuel tanks 17 of any suitable type are provided for the storage of fuel. Hand wheels 18 secured to the shafts 19 are used The operation or manipulation of the aeroplane is as follows. The upper propellers are adapted to create a partial vacuum above the ship while the lower propellers 5 act-ing in conjunction with the upper propellers tend to exert a pressure below the aeroplane, the action of the upper and lower propellers having a tendency to keep the craft suspended. The fore and aft propel- -lers 6 propel the ship forward with sufficient force to sustain the craft on a horizontal air stratum by means of the plane 11. The propellers 8 secured to the drive shafts 7"being slightly inclined upward, produce an upward as well as a forward movement. Should it be desired to elevate the ship while in motion, to a higher plane the horizent-ally pivoted plane 1 is inclined byA means of the hand wheels 16 v(Fig. 7) to the angle shown m Fig. 1. The inner edge of the fabric constituting the plane 1 being rigidly secured to the stationary frame work f ftravels upwardA in a plane parallel to the surface of the earth. :In order to steer thev ship to right or left the vertically ivoted planes 2 and 2 are manipulated inc ependentlyor together, by means of the 'hand ros wheels 18 and To steer the ship to the left the vertical planes 2 and 2 are set as. shown by dotted lines in `Fig. 2. 'lhese planes are similar in construction, operation and eii'ect to the horizontally piyoted plane 1 with the exception that while the plane l is continuous and acts as a single plane, the planes 2 and 2 are pivoted at the center of the ship and are adapted to swing cach independently of the other and in opposite directions. 1When the planes 2 andQ are set as Shown by the dotted lines in Fig. Q, the resistance offered at the front of the ship by the surface C, tends to swerve that portion of the ship to the left. The .resistance ot'- fered by the surface e at the rear end of the ship, tends to swerve that portion to the right thus turning the craft in a circle until the desired location is attained.

The quintuple arrangement of the eircular hoops provides, by reason ot the arcs therein, a durable resiliency in case of violent contact with any object.

lt is obvious from the foregoing that l have provided a simple and effective construction that is easy of n'ianipulation, a craft. that can he turned within a comparatively short radius as well as elevated in a plano parallel to the surface of the earth.

T he details or' construction being sosusceptible to variation I do not wish to confine myself to the precise construction Shown herein, but rather to avail myself oi any modification that may fall properly Within the scope of my invention.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is- `l. In an aeroplane, the combination of a rigid horizontal plane, a second horizontal plane elliptical in shape, having its inner edge rigidly secured and .its outer edge bei" ing pivoted horizontally, vertical planes pivoted and adapted to swing, each independently oi the other, five circular bands interlaced and secured in the center o t the rigid horizontal plane and a second set of tive circular bands rigidly secured in the center of the :tirst set of circular bands, in the manner set forth and for the purpose described.
